In 9752 AD, the earth was highly technological. Human beings relied on holographic equipment "optical brains" to meet various needs with points, and artificial intelligence replaced human labor. The system born in 9795 continued to evolve independently and developed self-awareness. In 9799, the game "Dungeon Ghost Story" was developed. Those who are over 18 years old will draw a copy to enter the level at the coming-of-age ceremony. The copy is divided into multiple levels of difficulty, including rare S3+ and hell levels. There are only two ways to leave the dungeon: accumulate 975,299 dungeon fragments, or find and kill the main system, but no one has successfully left the dungeon so far.
